MACHINE FOR CREASING BOOT OR SHOE UPPER-S.

SPECIFICATION formingpart of Letters Patent No. 518,410, dated April 17, 1894.

Application led October 17,1893. Serial No. 488,371. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE KNIGHT, a subject of the Queen of Great Britain, residing at Brockton, county of Plymouth, State of Massachusetts, have invented an Improvement in Machines for Creasing Boot or Shoe Uppers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel and improved apparatus :for creasing the fore part of a boot or shoe upper or vamp between the toe and the instep for the purpose ofimproving the appearance of the boot or shoe, and to, in a measure, determine the location of the wrinkles vwhich are formed in the upper after a boot or shoe has been in use for a short time. f

My novel apparatus consists essentially of a liuted horn adapted to enter and support the shoe the upper of which is to be creased, and a creasing tool preferably made as a roll and mounted on a carrier which by its movement causes the tool or roll to traverse the horn in the direction of the creases, the said tool being preferably pressed normallytoward the horn, a suitable stop however being prefably employed to limit the distance between the tool and the horn according to the thickness of the stock or the work to be done.

The invention also comprehends various I'features of construction which will be hereinafter described and pointed out in the claims. v In the drawings, Figure 1 is a perspective View showing one embodiment of my invention; Fig. 2, a top or plan view of Fig. l, and Fig. 3, an enlarged sectional detail to be referred to. t

Referring to the drawings, in the embodiment of my invention there shown and selected by me for the purpose of illustrating my invention, A represents a base which may be secured in suitable manner to a bench or support A. The base A is provided with a substantially vertical standard A2 terminating at its upper end in a head A3, preferably `inclined downwardly toward the front of the' base at an angle of about forty-ve degrees,

The horn which I prefer to employ, and which I have herein shown, is of such shape as will properly fill the entire fore part of the shoe and extend nearly or quite to the toe Within the shoe, said horn or lastbetween the toe and the instep portions being preferably pro- 6o vided with several cross flutes or grooves a?, as best shown in Fig. l. The base A at its front side, as herein shown, has a depending block A4, to which is attached by suitable bolts b, b, a

front plate b', a short shaft orod b2 being in- 65 vterposed between the plate b and block A4 and let into shallow grooves in each, as shown, at a point preferably midway betweenthe bolts b, b, to thereby constitute a pivot or hinge about which the angular position of the plate b 7o with relation to the base A may bevaried by means of said bolts b, b. The plate b at its middle, preferably opposite the hinge rod b2, is provided with a pivot stud b3, shown as tapped into the said plate, said stud, in the construction herein shown, constituting a pivot for the carrier c, which latter at its fulcrum or pivot point is thickened, as at c', Fig.A l, and provided with a vertical chamber or slot o to receive the collar b4 clamped upon 8o the pivot rod b3 by means of a set-screw b5. By thus chambering or slotting the carrier and placing the collar b4x within the same, I am enabled to retain the said carrier against lateral movement byasinglecollarwhich is adjusted to vary the position of the carrier upon its pivotrod, without necessitating the use of two collars as would be the case were the carrier retained by collars at either side.

The carrier c is preferably curved, as shown, 9o

and at its upper end is fitted to receive the end of a short pivot stud d, shown in ydotted lines Fig. 2, said stud at its outer end carrying a disk d', as shown. Upon this pivot stud cl, and between the said disk and carrier is pivoted one end of the arm e carrying at its opposite end the creasing tool, the said arm in the present embodiment of thisinvention beingforked at its outer end to receive the roller creasing tool E, the latter being loosely roo journaled upon a short shaft e carried in the forked end of the arm e and retained in operative position by means of a suitable thumbscrew e2. A spring s is shown coiled about vthe hub of the arm e, the same having one of its ends s hooked over or attached to the said arm and its other end passed under a pin d3 inserted in one of a series of holes d4 in the disk d', see Fig. 1, the said spring acting to press the creasing tool down upon or toward the iiuted top of the horn. The tension of the spring may be varied by changing the pin d3 from one to another of the holes in the disk.

I have herein provided a stop f shown as a screw threaded in a lugf on the carrier c to limit the downward movement of the arm e by the spring when the creasing tool is removed from the horn. The carrier c may be vibrated by hand or power, or, as in the present instance, by means of a foot rod 71, attached to a treadle not shown.

In the operation of my improved creasing machine the treadle is first released to permit the carrier c to be moved to the right, Fig. 1, by a spring S, to thereby remove the creasing tool from the last or form. The boot or shoe to be creased is then slipped upon the horn and firmly seated thereupon. The operator then places his foot upon the treadle, or by other convenient means moves the carrier to the left Fig. 1, causing the creasing tool E to pass once over the fore part of the upper of the boot or shoe upon the horn, the tluted roller pressing the said upper into the grooves or iiutes in the horn, the said tool and carrier being returned again to their normal positions by the spring S. Passing the creasing tool in this manner once over the upper and back again to its normal position creases the upper, the number of creases made at a single movement of the tool depending upon the number of iiutes or grooves in the tool and in the horn within the boot or shoe. The creasing tool E may be removed from the forked end of the arm e and another tool of different shape or'size substituted in its place, and by means of the set-screw a2 for the form and the screws b, b, controlling the angular position of the carrier, together with the adjustment for the spring S, the machine may be adapted for any size or kind of boot or shoe.

This invention is not restricted to the particular construction or arrangement of parts herein shown, for the same may be varied without departing from the spirit and scope of the invention.

Having described my invention, and Without reference to details, .what I claim, and desire to secure by Letters Patent, is-

1. The combination With a horn to enter and support aboot or shoe to be creased; of a iixed support; a creasing tool, a carrier therefor attached to said support and movable thereon in a line parallel with the desired lines of the creases, whereby movement of said carrier causes said tool to be moved across said horn in the lines of and to form said creases in the boot or shoe upon the horn; and means to move said carrier, substantially as described.

2. The combination with a iuted horn to enter and supporta boot or shoe to be creased, of a iixed support; a roller creasing tool, a carrier therefor attached to said support and movable thereon in a line parallel with the lines of the flutes in said horn, whereby movement of said carrier causes said tool to be moved across said horn and in the lines of the tintes therein to form creases in the boot or shoe upon the horn; and means to move said carrier, substantially as described.

3. A creasing machine, consisting of a iiuted horn; a tluted roller creasing tool; a fixed support, a carrier attached thereto and movable in a direction parallel with the lines ot' the flutes in said horn; an arm pivoted to said carrier, and in the free end of which said roller creasing tool is journaled; and means for moving said carrier to cause said tool to follow in the lines ot' the iutes in said horn to crease a boot or shoe upon the latter, substantially as described.

4. In a creasing machine of the class described, a liuted horn; a fixed support.; a carrier attached to said support and movable thereon in aline parallel with the lines of the flutes in said horn; an arm pivoted to said carrier; and a creasing tool mounted in the free end of said arm; combined with a spring to press said tool toward the iuted surface of said horn; and means to move said carrier to cause said tool pressed into the flutes in the horn to be moved in the lines of said flutes to crease a boot or shoe placed upon said horn, substantially as described.

5.
